 Jaynes–Cummings–Hubbard model

The Jaynes-Cummings-Hubbard model is a theoretical framework used in quantum optics and condensed matter physics to describe the interaction between light and matter within a lattice structure. It combines elements of the Jaynes-Cummings model, which describes the interaction between a single two-level atom and a single mode of the electromagnetic field, with aspects of the Hubbard model, which addresses the behavior of particles (typically electrons) in a lattice, accounting for both hopping between sites and interactions between particles.
